The emergence of modern data-intensive applications requires sophisticated database techniques for processing advanced types of user queries on massive data. In this paper, we study such a new type of query, called progressive queries. A progressive query is defined as a set of interrelated and incrementally formulated step-queries. A step-query in a… (More)

Handwritten Numeral recognition plays a vital role in postal automation services especially in countries like India where multiple languages and scripts are used Discrete Hidden Markov Model (HMM) and hybrid of Neural Network (NN) and HMM are popular methods in handwritten word recognition system. The hybrid system gives better recognition result due to… (More)

Meckel's cave (trigeminal cave or meckel's cavity) is a cerebrospinal fluid containing arachnoid pouch protruding from the posterior cranial fossa and houses the trigeminal ganglion. Meckel's cave tumors account for only 0.5 % of all intracranial tumors and the most common pathologies at this location include meningiomas and schwanomas (1,2). Central… (More)

IDS which are increasingly a key part of system defense are used to identify abnormal activities in a computer system. In general, the traditional intrusion detection relies on the extensive knowledge of security experts, in particular, on their familiarity with the computer system to be protected. To reduce this dependence, various data-mining and machine… (More)

Survival rates for infants and children who have choledochal cyst with or without spontaneous rupture have improved dramatically in the past decades. Despite excellent long-term survival for patients with choledochal cyst who undergo elective surgery, many significant complications can occur in the patients being operated in emergency for rupture of the… (More)

We provide a detailed study of the application of wireless sensor networks to a real-world building management system. A set of design requirements was discussed for the development of a sensor network architecture for an HVAC control system. We propose a system architecture that can be easily integrated into any existing building control system. We… (More)
